The entire entry (also in Photius: pi 472 Theodoridis) is a garbled version of Aelius Dionysius pi10, with the point of the entry obscured by inaccuracies. Dionysius is criticizing those who write the word with internal assimilation (passudi/ or passudei/, rather than pansudi/ or pansudei/) which Dionysius considers un-Thucydidean. The version here makes it seems as if the controversy is between passudi/ and the variant, homophonous in late Greek, passudei/. The major mss of Thucydides (see n. 2 below) read pansudi/, though the variants with internal assimilation and the -ei/ ending are attested in scholia and commentaries.
[1] The numeral 8 should be explicit, as in the earlier lexica, but has become here corrupted into 'if', the supposed first word of the quotation, for which see next note
[2] A garbled quotation of Thucydides 8.1.1, on Athenian incredulity at early reports of the destruction of their forces in Sicily (web address 1); quoted more accurately by Aelius Dionysius (see previous note).
